Malware Miscellany, September 2009




Top 3 countries for malicious URLs

Canada takes first place, hosting more than 21% of the world’s malicious URLs. The US is second with 16%, followed by China with 15%.


Top 3 countries hosting sites which spread malware

China claims first place, hosting 26% of all malicious sites globally.  The US comes second with 18%, and Russia is third with 12%.


Malicious site which affects the biggest number of Internet users accounted for 1.62% of all online infections globally.  This is a porn site located in China. Porn always attracts a lot of visitors, and it’s no secret that it’s often used by cybercriminals to spread malicious or suspicious content.  There’ve been attempts (which were blocked) to spread a wide variety of Trojans from this site – most of them are Trojan-Downloader.Win32.Agent and Trojan.Win32.StartPage variants.


Site spreading the biggest number of unique malicious programs

1142 unique malicious programs were spread from  The programs vary widely, and cover virtually all the different types of malware behavior in Kaspersky Lab’s classification.


Biggest malicious program

In September, this category was led by Trojan.Win32.Chifrax.d at 388 MB.  There are numerous modifications of this Trojan, all larger than 300 MB. Trojan.Win32.Chifrax.d is the name used to detect CAB archives which have been specially modified by virus writers in order to evade antivirus solutions.


Smallest malicious program

Trojan.BAT.Shutdown.ab is a mere 30 bytes.  It’s part of another Trojan that uses it to shut down the victim’s computer without asking the user’s consent.


Most widespread vulnerability on users’ computers

In late July, Adobe Flash Players 9 and 10 were found to have multiple vulnerabilities that can be exploited by cybercriminals to gain access to a system, run arbitrary code, gain access to confidential data or bypass security systems.  More information about the vulnerabilities and how to fix them, can be found at:


Most common exploit

Exploit.JS.DirektShow: in combination with Exploit.Win32.DirektShow, this malware family exploits a critical vulnerability in Internet Explorer 6.0 and 7.0 and has recently become extremely widespread on the Internet.


Most widespread malware on the Internet

In just a month, Packed.Win32.TDSS.z tried to penetrate computers in 108 countries around the world.


Worst joke (hoax programs that scare or annoy users but don’t have a clearly malicious payload)

Hoax.JS.Agent.c displays an obscene video clip and bombards victims with offensive messages which can’t be stopped.
